## Why list_capabilities is rated Low

This tool performs a straightforward read operation—it enumerates available templates and scene types to inform the user or agent about what DemoStudio can do. It has no side effects, does not execute code, does not modify any data, and does not commit financial or destructive actions. The blast radius of misuse is minimal; an agent could at worst spam requests, but the tool itself is informational only.

From the tool's own definition: "Tool name 'list_capabilities' and description 'List all scene types and Remotion motion-graphic templates available' indicate a query operation that retrieves and displays information about available features without modifying, executing, or deleting any data."

## Use case

AI agents call list_capabilities to retrieve information from DemoStudio without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches DemoStudio:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_capabilities": {}
  }
}
```
